To allow a car to shut off a number of cylinders, you need to know how much power the car needs when cruising.

If for example, it was a light car and only needed the power of 2 (Out of its 4) cylinders when cruising, then deactivating the other 2 would work.

However, if you deactivate too many cylinders, the car will not have enough power to cruise - like throwing your car in 5th at 20mph, it might keep going, but it wont like it.


About the vibration issue... VW, Porsche and Subaru have your answer. Flat 4/6 cylinder engines, by design they are almost perfectly balanced. Deactivating 2 out of 4 cylinders would not cause any extra vibrations.
